Now, to get to the number of neutrons, what we do is go up here to the upper left.
现在,看看中子数,我们要做的,是看到这左上方。
This means you can vary the neutron number without changing chemical identity, because chemical identity is fixed by the proton.
这表示你可以改变中子数,而不会改变它的化学特性,因为化学特性是由质子决定的。
And, if the conditions are right, they will combine, fuse and form darmstadtium plus neutron.
如果条件是正确的,它们将会结合,融合并形成鐽中子。
And carbon 14, 6 again and it has 8, and it is found in vanishingly small amounts, 10 10 to the minus 12 or part per trillion.
碳14,6个质子,8个中子,它的存在是非常微小的,几乎趋于零,万亿分之。
They all have the same Z, the same proton number, but different A, which means number of neutrons varies.
有相同的Z,相同的质子数,但是不同的A,也就是中子数不同。
